Republican EPA chiefs to Congress: Act on climate
By DINA CAPPIELLO 9 hours ago

WASHINGTON (AP) — Senate Democrats asked the heads of the Environmental Protection Agency for Richard Nixon, George H.W. Bush, George W. Bush and Ronald Reagan to discuss the risks from climate change and what should be done about it.

"We have a scientific consensus around this issue. We also need a political consensus," said Christine Todd Whitman, the former New Jersey Governor and first EPA administrator under President George W. Bush, who resigned her post after disagreeing with the White House's direction on pollution rules.

Whitman was joined by William Ruckelshaus, the nation's first EPA administrator under President Richard Nixon, William Reilly, who led the EPA under President George H.W. Bush, and Lee Thomas, who was administrator under Reagan.

The EPA chiefs' testimony apparently did little to bridge the divide.
